Serena Williams ruthless against Michaella Krajicek

Serena Williams needed just 49 minutes to win her second round match at the US Open against Michaella Krajicek with a 6-0 6-1 score. Should we even mention the statistics? Serena hit 10 aces and 25 winners to Krajicek's one ace and five winners.

In the first round Serena demolished Bojana Jovanovski 6-1 6-1, so she has lost only three games to reach the third round.

The 183th-ranked Krajicek, winner of three WTA titles which all came in 2006 or earlier, played Wimbledon quarterfinals in 2007 and had a career-high of No.30 in February 2008, but finished that season ranked No.219 due to injuries, which was her first non-Top 100 season since 2004.
